New features and improvements

Support for CUCM Extension Mobility

The Extension Mobility feature allows you to log in to a

TelePresence endpoint with your personal credentials. It is

well suited for endpoints that will be used by several users.

The feature is fully managed from CUCM (Cisco Unified

Communication Manager), and no further configuration is

required on the endpoint.

When a user logs in, the endpoint adopts the individual user’s

default device profile information, including line numbers,

speed dials, services links, and other user-specific properties

of an endpoint. When another user logs in, the settings and

properties change to match the new user.

For details on how to setup Extension Mobility, please refer

to the Features and Services guide for CUCM at 

Support for non-persistent mode

As a general rule, we recommend not to change the default

settings for persistency. This means that configurations, call

history, internal logs, local phonebook / favorites list and

IP connectivity information are stored, and a system restart

does not delete the information.

In the case were a new user is not supposed to see or trace

back to any kind of logged information from the previous

session, non-persistent mode may be switched on. In this

mode the configurations etc. are stored only in RAM, and will

be wiped at every shutdown. The persistency settings can

be configured from the Configuration > Security page on the

web interface.

Support for new languages on Touch 8

The following new languages are supported on Touch 8:

Arabic and Hebrew.

ICE support on Active control

Active Control (introduced in TC6.2) now has ICE support

(Interactive Connectivity Establishment, RFC 5245) when

registered to a VCS. This means that ICE and Active Control

can be used at the same time in this case.

Improved quality for presentation sources

An input source is fed directly to the encoder. The resolution

is not changed as long as it does not exceed the endpoint’s

maximum supported resolution and there are no bandwidth

restrictions. If the image must be resized to fit a recipient’s

screen, the scaling is performed after decoding on the far

end.

This leads to improved quality for presentation sources that

have other resolutions than the traditional video resolutions.

Automatic echo reference delay detection in high latency

environments

Automatic delay detection is introduced for high latency

environments; in earlier TC software releases the delay had

to be set manually. This makes it easier to configure the echo

cancellation correctly when high latency monitors and HDMI

audio output are used. This is typically the case for consumer

TVs with image processing.

Call History extensions

More detailed information is included in the Call History, for

example packet loss and jitter for each audio and video

stream in a call. Commands to query the Call History are

added to the API (xCommand CallHistory).

The Call History list is available in the web interface (choose

Call Control > Call History in the navigation bar ). You can use

the web interface to delete entries or clear the complete list.

You can download the Call History in an archive together with

the log files if you choose Diagnostics > Log Files in the web

interface navigation bar.
